Hi,
I managed to use the attached data set and figure out the following:
flies <-
read.table("example12_1.dat",header=TRUE,sep="\t")
boxplot(long ~ group,
data = flies,
horizontal = TRUE,
col = "red")
I'm very new to R and would like some help with the following:
1. Change the order on the y-axis from 1, 2, 3, 4, 5 to 5, 4, 3, 2, 1. In other
words, I want the bottom boxplot on top.
2. I want the y-axis labels 1, 2, 3, 4, 5 to read Group 1, Group 2, Group 3,
Group 4, and Group 5, and I would like them to be horizontal; i.e. parallel to
the boxplots.
3. I'd like the tick marks and labels on the horizontal axis to go from 10
to 110 by 20's.
4. Finally, I want to turn off the frame surrounding the image, but not the
horizontal axis and its tick marks and labels.
I appreciate the help.
Thanks.
David
Looks like data was not attached.

If you read the posting guide you will see that only a few types of attachments will be allowed through.

First make groups into a factor and then modify the factor levels. The default for the factor would be in numerical order 1, 2, ... but by listing the levels in reverse order the plot comes out the way you want. Changing the levels from 5, 4, ... to Group 5, Group 4, ... takes care of the labels on the boxplot although you could also use the names= argument in boxplot to do that.> flies$group <- factor(flies$group, 5:1) # Request 1 > levels(flies$group) <- paste0("Group ", 5:1) # Request 2Now insert the pars= argument to handle #3 and set up #4.

Added your code:
flies <-
read.table("example12_1.dat",header=TRUE,sep="\t")
flies$group <- factor(flies$group,5:1)
levels(flies$group) <- paste0("Group ",5:1)
boxplot(long ~ group,
data = flies,
pars = list(las=1, ylim=c(10,110), xaxt="n",
bty="n"),
horizontal = TRUE,
col = "red")
axis(1,at=seq(10,110,20))
Almost worked perfectly, except the frame around the plot remains, which is
strange as you have bty="n".

Sorry about that. I got rid of the box another way and then switched to using
parswithout making sure it worked. This works:
flies$group <- factor(flies$group, 5:1) # 1
levels(flies$group) <- paste0("Group ", 5:1) # 2
oldpar <- par(bty="n")
boxplot(long ~ group,
data = flies,
pars=list(las=1, ylim=c(10, 110), xaxt="n"),
horizontal = TRUE,
col = "red")
axis(1, at=seq(10, 110, 20))
par(oldpar)
